Determining if an address is valid prior to using it.

[jimmie.davis@l-3com.com]

Given an arbitrary address, is it possible to test and see if it is in
the process's address space ?

My current technique is to create a new thread, then access the memory
from that thread.  Then if it did not segfault i know the address was
valid.


Is there a better way to do this ?


thanks,
